JAMES HOOKING AND CLEMENT R. JONES, OF BENTON, NEBRASKA.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 296,171, dated April 1, 1884.

Application filed December 31, 1883. (No model.)

To all whom it may concern Be it known that we, JAMES HOOKING and CLEMENT R. JONES, citizens of the United States, residing at Denton, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in \Vagon-Brakes, of which the following is adescription.

Ourinvention relates to wagon-brakes which are automatically applied by the back-thrust of the team; and it consists in the peculiar construction and arrangement of devices in a single-horse vehicle for accomplishing this result, as will be hereinafter fully described.

Figure 1 is a plan view of a portion of the running-gear, with the body of the vehicle removed and showing the application of the brakes. Fig. 2 is a vertical longitudinal section of the same.

In the drawings, A A are two iron rods running under the shafts, and provided with loops a c, to receive the thill-straps. These rods A are guided in staples, so as to be capable of a longitudinal movement.

B is a whifietree below the shafts, and to which the rear ends of rods A are attached.

0 C are two wooden cross-braces between the shafts.

D is the ordinary whiffietree arranged above the shafts, which is connected to the lower whiiifiet-ree by a bolt, E.

F F are two iron plates fastened between braces G 0, parallel to the shafts, and having a central slot in them, through which the bolt E passes.

G is a bifurcated bar, whose front end'runs above and below the bar O, and connects with the upper and lower whiffletree, and whose rear end is connected by a universal joint, H, to the brake-bar I at a point near the kingbolt, to permit the shafts to be raised and lowered, and to move from side to side with: out disconnecting or cramping the brake mechanism. The brake-rod is slotted longitudinally where it passes over the front axle, and through this slot passes a king-bolt, which is v, provided with a friction-roller, K, to reduce friction and prevent binding. The brake-rod I diverges to the rear in two branches, L L, which connect at their rear ends with the downwardlyprojecting arms M M of a rockshaft, B. This shaft is arranged transversely to the vehicle beneath the wagon-body, and carries other downwardly-projecting arms, S S,

which are provided with brake-shoes, which, when arms M are thrust to the rear, arebrought forcibly against the wheels to stop their revolution.

From the rock-shaft B there projects another arm, N, connected by rod 0 with a lever, 0, which is provided with a lockingbar, O, engaging with a curvednotch bar, 0

Now, for applying the brakes automatically by the back-thrust of the team, the lockingbar O being held out of engagement with the notched bar 0, whenever the team thrusts backwardly, or the wagon runs upon the team,

the thill-straps force back the rods A, and,-

driving back the whiffletrees and bars G I L, rock the shaft E- and apply the brakes.

To apply the brakes by hand, the train of mechanism N O O O" O is employed, and this mechanism also serves to lock the brakes, so as to prevent them from being applied when backing.

hen the automatic brake is to be kept in operative condition, the locking-bar O is held out of engagement with the notched bar by a link, 0'.

Having thus described our invention, what weclaim as new is- 1. The combination, with the rock-shaft R, having downwardly-projecting arms S, hearing brakeshoes, and downwardly-projecting arm M, of the branched brake-rod I L, slotted and guided bya vertical bolt, and means, substantially as described, for forcing the same backward, as set forth.

2. The combination, with the shafts of avehicle, of the rods A, having loops a, and

guided beneath the shafts, the singletrces B B, guide-irons F F, bifurcated bar G, and a brake-bar connecting with the brakes, and adapted to apply the same when the rods A A are forced back, as set forth.

3. The. combination of rock-shaft R, having brake-shoe arms S and arm M, the brakerod I L, the bifurcated bar G, connected to brakerod by a universal joint, H, the single-trees B D, and the shaft-rods A A, as and for the purpose described.
